OBJECTIVE
The neonatal mortality rate (NMR) continues to remain quite high, one important cause being preterm deliveries. The main obstacle in the pathway towards decreasing NMR is identification of babies in need of extra care. To analyze the utility of newborn foot length as a proxy measure for birth weight and gestational age.
METHODS
A cross-sectional study done in a hospital of eastern India with 351 babies during 4 months. Right foot length of each recorded using a plastic, stiff ruler.
FINDINGS
48.1% babies were preterm, 51.8% low birth weight (LBW) and 33.3% very low birth weight (VLBW). Foot length less than 7.75 cm has 92.3% sensitivity and 86.3% specificity for identification of preterm neonates. For identification of LBW babies (<2500 gm) a foot length less than 7.85cm has 100% sensitivity and 95.3% specificity. Foot length less than 6.85 cm has 100% sensitivity and 94.9% specifity for identification of VLBW babies (<1500 gm).
CONCLUSION
Foot length may be used in the identification of LBW and preterm babies who are in need of extra care.
目的
新生儿死亡率仍然很高，早产是一个重要原因。降低新生儿死亡率的主要障碍是识别需要额外护理的婴儿。分析新生儿足长作为出生体重和胎龄替代指标的效用。
方法
在印度东部一家医院进行的一项横断面研究，在4个月内对351名婴儿进行研究。使用塑料硬尺记录每个婴儿的右脚长度。
结果
48.1%的婴儿为早产儿，51.8%为低出生体重儿（LBW），33.3%为极低出生体重儿（VLBW）。足长小于7.75厘米对识别早产新生儿的敏感性为92.3%，特异性为86.3%。对于识别低出生体重儿（<2500克），足长小于7.85厘米的敏感性为100%，特异性为95.3%。足长小于6.85厘米对识别极低出生体重儿（<1500克）的敏感性为100%，特异性为94.9%。
结论
足长可用于识别需要额外护理的低出生体重儿和早产儿。
